PIRTEK Centers have recently added custom built O-Ring Kits due to popular demand. The ORK-C4 kits are specifically designed to provide O-Rings for all of the popular hose fittings and adapters. Carrying these kits in your facility or service trucks gives your technicians the availability of having popular O-Ring sizes for hydraulic fittings and adapters on hand in one kit. The O-Ring Kits consist of a carry case, four separate product boxes with PIRTEK branding and a description of the contents of each box. The O-Rings supplied in these kits are suitable for S.A.E. Flanges, Flat Face O.R.F.S. and O-Ring Boss Male fittings.
